HUMIDIFYING DEVICE Filed Nov. 28, 1930 INVENTOR ZEEEET 3 c/OYDfl/Y BY wmug ATTOR N EYS Patented Sept. 6 1932 PATENT OFFICE LEIBEBT E. lrommn,or MINNEAPOLIS, mascara mmmrrrms DEVICE Application filed November 28,1930. Serial No. 498,629.

This invention relates to an auxiliary heater and an auxiliaryhumidifyiug device adapted to be used in connection with a furnace.While the device is applicable for use with various types of furnaces,itparticularly is designed for use in connection with an oil burningfurnace. There is often insuflicient radiating surface to properly-usethe heat generated in an oil burner, and undesirable stack temperaturesoften result. It is desirable to have the airsupplied to living rooms ata certain degree of humidity, and the importance of this is emphasizedtoday by heating engineers. It is an object of this invention to providea simple and eflicient device for receiving the products of combustionfrom a furnace, using the heat thereof to heat air which is supplied toliving rooms and at the same time supply humidity to said air. I

i It is another object of the invention to provide a device comprising acasing containing a water pan or receptacle, means for direct ing airover the water means for heating said 2 air from the products ofcombustion of the furnace, said device having a chamber into which saidair is delivered, and from which conduits lead to the rooms to besupplied with heated air.

It is more specifically an object of the in vention to provide a devicecomprising a casing, a water container in said casing,'a plurality ofspaced conduits having 0 n ends one of whichis disposed adjacent t ewater in said container, said conduits communicating with a commonchamber in said casing, a pair of conduits communicating with salddevice at-opposite sides, and adapted to be connected respectively tothe smoke pipe of a furnace and to the chimney, the gases passingthrough said last mentioned conduits passing around said water containerto heat.

the water therein and the air passing through said first mentionedconduits.

These and other objects and advantages of the invention will be fullyset forth in the following description made in connection with theaccompanying drawing, in which like'reference characters refer tosimilar parts throughout the several views, which Fig. 1 is aperspectiveview of the device, certain parts being broken away to show the interiorthereof;

Referring to the drawing, a device is shown comprising a casing 10.While this casing might be made of various forms, in the em bodiment ofthe invention illustrated it is shown as of rectangular form andelongated.

A conduit 11 communicates with the bottom 55 of casing 10 centrallythereof, said conduit having a flan e 11a secured to the bottom ofcasing 10. asing 10 has a pair of spaced partitions 10a secured to itsends, the same shown as having out-turned flanges at their ends securedto the ends of casing 10. These partitions 10a are connected at theirbottom by a plate 100, the plates 10a and 100 thus forming three sidesof a rectangular casing, and the plate 106 extends between plates 10a ashort distance below their top edges, this plate extending to the endsof casing 10. A

rectangular casing 12 extends downward from the central portion of plate106, said casing 12 being adapted to form a water receptacle, and thewater may also be contained in the pan formed between the plates orpartitions 10a and the ends of casing 10, the water being represented inFig. 4 as 12a. The plates 10a, 10b and 100 form a rectangular casingdisposed within casing 10. It is desired to maintain a certain level ofwater in casing 12 and the pan thereabove. While a suitable means may beused for maintaining such level, in the'embodiment of the inventionillustrated a float 13 is used, secured to a lever 14 pivoted at 16 to avalve and bracket 17 secured to a pipe 18 extending through the end ofcasing 12 and through the end of casing 10. This pipe will be secured tothe end of casing 10 by a suitable coupling 19. A motor 20 illustratedas of the electrical type is mounted upon a suitable supporting meanssuch as the legs 21, which will rest upon the floor or other supportingsurface.

v vertically extending passages 24 between the dMotor2O has a fan 22secured its shaft which is located axially below theconduit l1 asshownin Fig. 2. a The partitions 100 form 1 through an opening in the plate10a to which it is secured. Casing 12 has a conduit 12?) extendingbetween its sides, said' conduit being axially alined with the conduits2'1 and 28 and being controlled by a damper member 25 secured to a rod25a having a crank on its end which in turn is pivotally secured to a.handle rod 26 extending through a tube 264 secured in one plate 10a andone side of the casing 10. Rod 26 has a ring 266 at its outer end andtube 26ais provided with a packing nut 260 at its outer end. It will beseen that damper 25 can be regulated by the rod 26. The conduit 27 isadapteddso be connected to the smoke pipe 29a of a furnace 29 and theconduit 28 is adapted to be connected to a. chimney 30. A conduit 31 hasan out-turned flange 31a secured to the top of casing 10 andcommunicates with the 1n-.

tcrior of the casin 10 through an opemng in the top thereo conduit 31preferably being'axially alined with conduit 11. .7

i In operation the conduit 31 will extend to one or more rooms to beheated, and motor20 will be driven. Air will be forced into conduit 11and this air will be deflected by the plate 100 and will pass around thepartitions 10a and into the chamber at the topof casing 10 over thewater in the pan at the top of casing 12 and out through the conduit 31as .indicated by thelarrows 32, The hot prod nets of combustion fromfurnace 29 will pass through'conduit27 and the same will pass around thebottom and ends of casing 12 as indicated bythe arrows 32 and will thenpass out through conduit-28 to the chimney. The casing 12 will be heatedas will the water therein, and the plates 10a and 100 will also beheated. Part of the water will be evaporated and will pass out with theair passing through conduit 31. This evaporation will be assisted by theair passing up around the plates 10a and over the top of thewater, sothat the air passing out through conduit 31 is well humidified. The airpassing in through conduit 11 will also beheated byits passage aroundthe plates 10c and 10a so that warm humidified air is supplied to therooms through conduit 31. The desired level of water will be maintainedby the float 13 regulating the valve 17. If a stronger or more directdraft is desired through the device, the damper 25 can be opened bymanipulating the operating rod 26; If this is done, the products ofcombustion can pass directly through the conduit 12?) and will not haveto pass around casing 12. The damper 25 will normally be closed.

From the above description it is seen that applicant has provided a verysimple heating and humidifying device. The excess heat in the productsof combustion from the furnace is utilized tovheat the air which isdelivered to the rooms to be heated, and to evaporate water to supplythe desired humidity- The apparatus is quite efiicient, as it uses onlyheat which would otherwise pass into the chimney and be lost. The deviceis simple in construction, can be inexpensively made and installed, andresults in quite a saving of fuel. The device has been amplydemonstrated in actual practice and found to be very successful andeflicient.
